A Red Sea specimen of the marine sponge Hyrtios erectus was found to contain three new alkaloids, hyrtioerectines A-C (1-3). Hyrtioerectine A (1) possesses the carbon bond-linked moieties 6-hydroxy beta-carboline and 6-hydroxyindole. The structure elucidation of 1-3 was based on intensive study of their spectral data including 1D (1H and 13C) and 2D (1H-1H COSY, HOHAHA, NOESY, ROESY, HMQC, and HMBC) NMR, together with high-resolution mass spectra. Hyrtioerectines A-C were moderately cytotoxic.
红海的一种海洋海绵直立扁枝海绵(Hyrtios erectus)被发现含有三种新生物碱,即直立扁枝海绵碱A - C(1 - 3)。直立扁枝海绵碱A(1)具有通过碳键连接的6 - 羟基β-咔啉和6 - 羟基吲哚部分。对1 - 3的结构解析基于对其光谱数据的深入研究,包括一维(1H和13C)和二维(1H - 1H COSY、HOHAHA、NOESY、ROESY、HMQC和HMBC)核磁共振谱,以及高分辨率质谱。直立扁枝海绵碱A - C具有中等细胞毒性。
